To all whom t may concern.' f

Beit known that we, ROBERT PEEL and Tiroinis FREDERICK Srrnvnns, both subjects of 'the King of Great Britain and ireland, and both residents of New Brancepeth Colliery, in the county of Durhani, England, have invented certain new and useful Improvements in or Relating to Coke-Oven Doors, of which the following is a specification.

This invention relates to coke ovens, and especially to doors for coke ovens. The object of this invention is to provide an irnproved door and means for supporting and protecting the coke oven end walls.

In accordance with this invention a cast iron frame is permanently fitted against the end of the oven so as to cover' the ends of the dividing walls, the upper part or web of the frame extending from wall to wall.

The upper part of the frame is or may be recessed and is or inay be provided with an aperture adapted to be closed by a door pivoted to the frame, or by a removable plug.

The lower part of the frame forins ansupport to the oven door.

Referring to the drawings filed herewith:-

Figure lis an elevation of one forni of door ina-de in accordance with this invention;

Fig. 2 is a cross-section on line 2--2, Fig. l;

Fig. 3 is a cross-section on line 8-3, Fig. l; and y Fig. l is a vertical section On line L -4, Fig. l.

At the ends of the dividing walls a a is mounted frame b. In the upper part of the frame is a flanged aperture o adapted to be closed by a door d hinged at c to the The door is provided with a fiange f, adapted to hold fire-brick lining.

The lower part of the frame is provided with a reveal g g which incloses the ends of the walls a et. The door /L is provided with flanges 7L which closely fit against the reveals g g. These reveals g g and the flanges h slope inwardly on the top and two sides so that the door fits the reveals as a wedge, the door sinking into the recess formed by the reveals sufficiently to form a ledge 7a2 adapted to hold a luting of clay. The door is adapted to be lined with `firebrick so that the flanges it and reveals g are sandwiched between brickwork which keep the doorand traine at an even te1nperaturc so that they will not become distorted and cracked. rl`he door is provided with a, link j by which it can be raised or lowered into position.

ln front of the fraine Z2 are disposed vertical angle iron standards 7c to which are secured cross rods m m, which coact with inclined planes 0 0, disposed in the door for the purpose of holding the saine in position in the frame o.

The door is adapted to be lined with firerick.

The upper door l when provided is -adapted for use for the purpose of leveling the coal charge. The lower door is large enough to enable the coke to be discharged.

A door inade in accordance with this invention can be readily lifted without damaging the brickwork. The frame gives support and protects the coke oven end walls. rllhe lifting door being lined gives protection to the charge and prevents what is known as cblackends.

The lifting door can be readily replaced should it become fractured. As the door fits into a frame it can be readily luted and rendered gas or air tight.

What we claim as our invention, and desire to secure by Letters Patent is l. lln coke ovens having dividing walls, a door frame permanently fitted against the end of the oven so as to inclose the end of the dividing walls, a web to said frame eX- tending from wall to wall, inwardly inclined reveals to said frame, a lifting door, inwardly inclined flanges to said door adapted to hold a firebrick lining, said flanges and reveals being sandwiched between brickwork, and means for lifting said door in and out of position.

2. ln coke ovens having dividing walls, a door frame permanently fitted against the end of the oven so as to inclose the ends of the dividing walls, a web to said frame eX- tending from wall to wall, an aperture in said web, n'ieans for closing said aperture, inwardly inclined webs to said franie, a lifting door, inwardly inclined flanges to said door adapted to fit said reveals, and adapted to hold a firebrick linking, said flanges and reveals being sandwiched between briokwork, and nieans for lifting said door in and out of position.

3. In coke ovens having dividing Walls, a door frame permanently fitted against the end of the oven so as to inelose the end of the dividing walls, a web to said frame extending from wall to Wall, inwardly inclined reveals to said frame, a lifting door, inwardly inclined flanges to said door adapted tohold a irebriek lining, said flanges and reveals being sandwiched between brick- Work, and means for lifting said door in and out of position, standards in front of said dooi1 frame, cross rods between said standards, inclined planes in saidfliiting door adapted to eoaet with said cross rods.

In testimony whereof we have signed oui1 names to this specification.
